Warning Warning Tc Air bag doesn't work!!!

[skyrollin]

i crash my tc over the weekend, it was raining, i was going fast and lost control, missed the electric polls, but hit the string that hold the poll stay up straight, but somehow the air bag DID NOT pop, my car is total now...i'll try to upload some pics if anyone wanna see it, so sad right now...

well.... the airbag is set off when specific sensors are triggered..

those sensors are placed in areas where when the airbag needs to go off.. they will.

it's not always bad that the airbag didn't go off.

Sorry to hear about your crash.
Could you explain more how you loss control.
Did the car understreer when you hit the pole?
Are your driving on stock suspension or is it modified?
Just curious how the car reacts in such a situation.

This is very true. For your enjoyment
1. DESCRIPTION OF SUPPLEMENTAL RESTRAINT
SYSTEM (SRS)
(a) General description
(1) In this system, the center airbag sensor installed
on the floor under the A/C unit determines
whether or not to activate the SRS airbags and
seat belt pretensioners by receiving the collision
signal from the airbag sensors (excluding the
center airbag sensor). When there is trouble in
the system, the center airbag sensor turns on
the SRS warning light on the combination meter
to inform the driver.
(b) Description of the dual stage control
(1) The center airbag sensor controls the dual stage
deployment of the driver airbag in the horn
button and the passenger airbag on the
instrument panel. The center airbag sensor
controls the dual stage deployment of the driver
airbag according to the collision impact, seat
position and seat belt ON/OFF state. It also
controls the dual stage deployment of the
passenger airbag according to the collision
impact.
(c) Description of check mode (signal check)
(1) This center airbag sensor can be operated using
the check mode of the intelligent tester function.
Check mode can detect and output DTC by
using the intelligent tester to switch the center
airbag sensor to the check mode.
A simulation method should be used if the
malfunction cannot be reproduced during
troubleshooting (the malfunction is temporarily
solved, etc.). In this case, joggling each
connector, or driving on a city or rough road with
the center airbag sensor in check mode makes it
possible to obtain a more accurate malfunction
condition.
2. IGNITION JUDGMENT AND CONDITIONS
(a) Operation in case of front collision
(1) When the vehicle collides in the hatched area
(Fig. 1) and shock is larger than a predetermined
level, the airbags (driver and front passenger)
are activated automatically. The deceleration
sensor of the center airbag sensor determines
the need for ignition in response to collisions
within the hatched area based on the signal from
the deceleration sensor of the front airbag
sensor.
RS–6 SUPPLEMENTAL RESTRAINT SYSTEM – AIRBAG SYSTEM
RS
(2) Safing sensor of the center airbag sensor is
designed to activate at a lower deceleration rate
than the deceleration sensor. As illustrated in
Fig. 2 below, when both the safing sensor and
deceleration sensor go on simultaneously,
current flows to the squib and ignition occurs.

your allways to techinical...

[SquallLHeart]

^^ heheh.... you haven't seen my technical side yet...

[ForBiddeN]

lol great cant wait to see it.

[navylife59]

Always back up your info with the facts on Forums. Keeps everyone happy

[SquallLHeart]

okay..

here's some stuff to add on to the "Ignition Judgment and Conditions" you stated above with a small repeat.. (also explains for those who have side curtains as well)

2. IGNITION JUDGMENT AND CONDITIONS

(a) Operation in case of front collision.

(1) When the vehicle collides in the hatched area (Fig. 1) and shock is larger than a predetermined level, the airbags (driver and front passenger) are activated automatically. The deceleration sensor of the center airbag sensor determines the need for ignition in response to collisions within the hatched area based on the signal from the deceleration sensor of the front airbag sensor.

(2) Safing sensor of the center airbag sensor is designed to activate at a smaller deceleration rate than the deceleration sensor. As illustrated in Fig. 2 below, when both the safing sensor and deceleration sensor go on simultaneously, current flows to the squib and ignition occurs.



(b) With side curtain shield airbag:

Operation in case of front side collision.

(1) Electronic safing sensor of the side airbag sensor is designed to activate at a smaller deceleration rate than the deceleration sensor of the side airbag sensor. As illustrated below, when both the safing sensor and deceleration sensor go on simultaneously, current flows to the squib and ignition occurs.



(c) With side and curtain shield airbag:

Operation in case of rear side collision.

(1) Electronic safing sensor of the center airbag sensor is designed to activate at a smaller deceleration rate than the deceleration sensor of the rear airbag sensor. As illustrated below, when both the safing sensor and deceleration sensor go on simultaneously, current flows to the squib and ignition occurs.

navy your to funny lol.
